Try the line below from a terminal.  This will install all of Octave's 
dependencies.

        apt-get build-deb octave3.6

After that you should be able to compile the developer's sources by ...

        ./bootstrap
        ./configure
        make

If you're building from a released tar-ball, then just ...

        ./configure
        make
